In the range $-4,0,$ find two zero places$/$roots: $a,b$ of the function $f(x)$ that is defined above.

Compare convergence $($number of the iterations needed to obtain solution$)$ with accuracies $={10}^{-4},$

${10}^{-5},{10}^{-6},{10}^{-7},{10}^{-8}$ of the secant and tangent methods. Print the table with a set of accuracies and

corresponding numbers of iteration. Create a pdf file Name$\_$task$2\_$nrN$.$pdf with the text of your code,

two roots, the table $N()$ for both roots, and Excel or Grapher plot $N()($Figure $3)$ with corresponding

labels.
